I am using filemanager on Z10 (STL100-3, 10.2.1.2977) to move music files from my device to media card. Filemanager moves them, however they still appear in device music file folder, appear to take up device space, but when you select the files they cannot be loaded. I have rebooted the phone, but the issue remains.

This is the first time I have come across this issue when moving multiple files from Music folder on the device to the Music folder on the media card.

When I select 15 files to move from the Device Music Dolder to the Media Card Music Folder the files are moved and copied to the Media Card Music Folder accurately....however "shadows" of the moved files seem to remain in the Device Music Folder but they cannot be accessed or deleted. Any attempt to delete or play file in the original device music directory gives the error... "Unable to open "FILENAME" "...

When I reboot the Z10 they are still there but over the course of a day or so the Z10 file system seems to rectify itself or catch up...This "lag error" is consistent and repeatable, but as consistently seems to eventually rectify itself. Very odd to have this significant delay.
Has anyone noticed this situation? Is there a way to have the Z10 file system update its files in near real time ?
